A wide variety of industries specialize in technologies that shape the spectrum of light reaching the eye from the environment; two significant examples are artificial illuminants (including traditional bulbs and LED light sources) and filtered lenses (including windows and eyewear).
Technologies of this kind can work effectively only by designing for the color vision humans actually possess. This, in turn, requires understanding the evolutionary design and function of color vision. Although key aspects of the mechanisms of color vision have long been understood, only recently has a major advance been made concerning its evolutionary function.
2AI is the intellectual source for this seminal discovery, which is that color vision is optimized for sensing the spectral modulations occurring on the bare skin of other people, providing the viewer with information about the other person's state, emotion, mood and health. The spectral modulations on skin are mediated by changes in the nature of the underlying blood, in particular by modulations to the concentration and oxygenation of hemoglobin.
Via comprehension of the hemoglobin spectrum underlying skin color signals and the visual mechanisms designed to detect them, 2AI's technology selectively enhances or attenuates the spectral signals to achieve various desired effects.
With a grasp of what color vision is for -- it is, more briefly, for seeing human skin and the signals it displays, via the mechanism of blood physiology modulations -- these new kinds of technologies suggest themselves. 2AI has unique expertise in designing light for human eyes, and possesses intellectual property behind new technologies with applications within a number of industries.
